Photosynthesis Under Field Conditions. IV. Light Studies with Individual Corn Leaves1

摘要: The shape of the light response curve individual leaves has recently become important in models for absorption by field crops. Studies corn under sunlight is discussed. A leaf chamber technique continuous measurement net assimilation CO/sub 2/ a or ear was developed. Uptake rates optimum were order 45 mg. per square decimeter area hour. Corn temperature and percent dry matter found to have marked effect on respiration rate. husks photosynthesized approximately 30 hour midday sun. 20 references, 5 figures, 3 tables.
